Ensures well integrity
- The connection minimizes the risk of jump out failures under bending loads. In addition, with at least twice the torque transfer compared to API connections, VAroughneck® is suitable for deviated wells, drilling with casing operations or the completion of extended reach wells.
Rotation during installation
Improves quality of cement bond
- The thread design offers the opportunity to rotate the casing string during installation. Due to the thread profile, the connection is able to handle axial loads without inducing high radial forces to pin and box.
Smooth internal profile
- The flush internal profile minimizes turbulences and provides good conditions for internal pipe coating.
Compatibility with API Buttress
- With the VAroughneck® thread design, the make-up is limited by pin-to-pin contact. VAroughneck® and API Buttress can be made-up together without using a crossover. If specific parts of the string require higher torque properties, they can be achieved by installing a spacer ring to occupy the J-Distance or by applying a thread locking compound, such as Bakerlok® or Tube-Lok.
